START WITH YOUR HOME, NOT A MODEL NUMBER

Find your generator size & budget.

No email required

Choose your coverage, adjust the appliances, and get a preliminary shortlist. Your answers stay in this page; nothing is submitted.

1. What do you want to back up?

Whole Home is a coverage goal, not a promise that every appliance can start or run together. Review every large load below.

2. What needs power?

Select equipment you have and want backed up. You can use the starting estimates or open the optional wattage controls. These are planning assumptions—not your appliance ratings.

This screens electrical demand; it does not determine motor-starting kVA, phase compatibility, gas supply, or a code-compliant installation. Heat strips and multiple HVAC units can substantially change the result.

3. Fuel & installation

*Limited warranties have exclusions and separate coverage terms. Champion transfer-switch coverage differs from generator coverage. Model prices are not verified. The planner uses a broad national installed-cost reference, not model-specific quotes.

LOOK SIDE BY SIDE

Your shortlist, without the noise.

Select up to three models above. Output, package contents, and fuel use belong in the same conversation.

Choose at least two models to compare.

PLAN FOR THE OUTAGE

What would the
fuel actually cost?

Explore propane costs at two published load points. A bigger generator’s 50% load is a different electrical demand; these estimates are not an equal-load efficiency ranking.

Estimated fuel expense

Fuel only. Excludes installation, maintenance, exercise cycles, and other costs. Actual consumption varies. Models with conflicting fuel data are excluded.

FOLLOW THE EVIDENCE

A missing number is better
than a made-up answer.

Every model links to the manufacturer. Conflicting fuel figures are flagged and excluded from estimates. We distinguish source facts from calculations, and leave unknowns visible.
